I am developing a VB.NET program to search for text in a specified column from a Datagrid. I am almost finished implementing this following the MS tutorial at:[url]But now I have just one compilation error:

Also, I'm not sure if it is good to be declaring these variables new like this since I believe I already call them new elsewhere in my code.

What should i do to resolve this problem?what should i use to define mathematical operators?
I haven't had this problem before. For some reason, when I declare a variable,I.E.rand as a new random(), and try to use rand.Next, i get an error saying 'Next' is not a member of system.array. Not sure why this is happening.
[Code]...
I'm having trouble understanding why i'm getting the error 'add is not a member of system.array'I'm using an arraylist and when I hover over my declaration of memberarray As ArrayList() the tooltip states 'Dim memberarray as System.Collections.ArrayList()[code]

I'm working with a listbox that has, let's say, 20 items. The size of the listbox allows the user to see the first 5 items. However, the listbox has one preselected item which is sometimes not visible because it isn't one of the first 5 items.
After I set the selected Item for the listbox how can I ensure that the lisbox is scrolled appropriately so that the selected item is visible to the user?

The exact error I am getting in Visual Studio 2012 is:
error BC30456: 'Dispose' is not a member of 'System.Net.Mail.SmtpClient'.
Dim SmtpServer As New SmtpClient()
Dim mail As New MailMessage()
SmtpServer.Port = 25
[code]....
This should be an obvious error. You would think I was using .net framework 3.5 or lower as Dispose() was only added as a member to SmtpClient in .net 4.0. However, I am using 4.0!In the website property pages it states 4.0. Is there somewhere else that I need to set as 4.0?
What i am having trouble doing is set the current parameter to the current row at a specific column like e.row[column index]

I have on my form two datagridviews that correspond to the same table. They are both databound. They have been created automatically through dragging them from the datasources windows.One is datagridview and the other datagridview1. When ever I navigate through a datagrid the corresponding row on the other grid changes as well. I do not want this. Also I want to be able to fill and use each datagrid indepentent from each other. To fill a datagridview on load I use this code
Me.AllServicesTableAdapter.workstation(Me.Database2DataSet.AllServices)This code does not let me choose which datagrid to fill.

I've been trying to translate some code from C# to VB.NET, but I have three lines in my translated code which are giving me headaches. All three of them read like this variable = Win32.CreateEvent(HANDLE.Zero, False, False, Nothing).The error is under HANDLE.Zero. Just like the subject line says, the error I am receiving is "'Zero' is not a member of 'System.Array'".HANDLE is declared as System.IntPtr.This is the relevant part of code in the Win32 class.
Public Shared Function CreateEvent(lpEventAttributes As IntPtr, bManualReset As Boolean, bInitialState As Boolean, lpName As String) As IntPtr
End Function
Below is the code for the complete Win32 class.
